What is the difference between acculturation, assimilation, and amalgamation?

Acculturation is one of several forms of culture contact, and has a couple of closely related terms, including assimilation and amalgamation. Although all three of these words refer to changes due to contact between different cultures, there are notable differences between them.
Acculturation is often tied to political conquest or expansion, and is applied to the process of change in beliefs or traditional practices that occurs when the cultural system of one group displaces that of another.
Assimilation refers to the process through which individuals and groups of differing heritages acquire the basic habits, attitudes, and mode of life of an embracing culture.
Amalgamation refers to a blending of cultures, rather than one group eliminating another (acculturation) or one group mixing itself into another (assimilation).
